The actual plan to evacuate Kherson was clearly made a while ago and the generals planning it did the right thing, they reinforced the Left bank, three trench lines, concrete pills boxes every 100 meters or so, so troops on the left bank could cover those retreating across the river
But I can't believe the public announcement was part of the plan as the final orders to retreat clearly hadn't been given and the NCOs and junior officers on the right bank clearly aren't capable of on the spot decision making (that is perfectly in line with Russian doctrine)
There's also a lot of other dumb stuff too, the Russians spent the last few days scuttling or removing outboard motors from all the civilian boats moored in Kherson, when there is a shortage of.... boats
It's basically become every man for himself on the right bank and they've herded themselves like sheep onto the riverbank waiting to cross, they are sitting ducks
That death count tomorrow is going to be the highest we've ever seen by some margin and it will now really only be a guess
The Russians also blew the railway bridge last night, which was the only way they had to get any heavy ordnance off the right bank. They probably needed to when they did it but they should have been getting it out of there slowly without the announcement being made
The importance to Putin of the home front propaganda over the lives of his men, his countrymen, the rump of his experienced contracted soldiers has cost them dearly
WIthout the strength on the left bank, they really might just have opened up Crimea and to defend the left bank, they will have to rapidly strengthen it but from where? It can only be strengthened with the mobilised and they won't last long and more importantly it will significantly weaken the other fronts.
This really could be a massive turning point
